More Information
W32/Agobot-AIU is a worm with IRC backdoor functionality for the Windows platform.
W32/Agobot-AIU spreads to other network computers by exploiting common buffer overflow vulnerabilities, including: PNP (MS05-039) and ASN.1 (MS04-007) and by copying itself to network shares protected by weak passwords.
W32/Agobot-AIU runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels.
When first run W32/Agobot-AIU copies itself to <System>\jvcsvc32.exe.
The following registry entries are created to run jvcsvc32.exe on startup:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
JvcHost
